The Catalan giants are keen to bring in a replacement for Henrik Larsson and have turned their attentions to the Iceland international.

According to El Mundo Deportivo, Barca have agreed on an amount to offer Chelsea after The Blues signalled that Gudjohnsen could leave for the right price.

Barcelona are said to be well aware of the interest from Manchester United&nbsp;but they are&nbsp;hoping that&nbsp;the Camp&nbsp;Nou&nbsp;club have an Ace up their sleeves.

Jorge Mendes is Deco, Rafa Marquez and Thiago Motta's agent, but, more importantly, he is also Jose Mourinho's representative and has a good relationship with Chelsea's Peter Kenyon.

Barca are hoping Mendes' relationship with the Blues&nbsp;executive will be the key to them securing the services of Gudjohnsen. Frank Rijkaard has told the board that he thinks&nbsp;the former Bolton Wanderers star is&nbsp;the perfect substitute for Larsson, who has returned to his native Sweden this season.

Barca were initially keen on signing Forlan from Villarreal, but talks between the two clubs and the player's agent, Daniel Bolotnicoff, have proved to be difficult with neither side willing to budge.

Villarreal want é¼15 million (&pound;10.34 million) for the former Manchester United forward, but Barca are hoping to reduce that sum by offering players in exchange, with Javier Saviola and Maxi Lopez included in any deal.
